CSTAR Telescope Array in China reached the highest point of the continental Antarctic Dome A
Following the January 18, 2005 for the first time for China to reach man of the field to reach the ice sheet of Antarctica after the peak of Dome A, 24 China Antarctic expedition icecap expedition team on January 12 2008, again called "not very close to humans," the highest point of the Antarctic continental ice dome A. The last difference is that the expedition, including Dome A survey of the Centre and the installation of our first comprehensive framework for CSTAR small optical telescope array for astronomical observation.
Antarctica Dome C has been confirmed on the ground is of the best astronomical observatory, according to the similarity of the terrain, the first Chinese scientific expedition team landed Dome A is likely to be a better place in the Centre, that Chinese astronomy provides an excellent development opportunity. In late 2006, Chinese astronomers and experts in astronomical instruments made the first astronomical equipment Antarctic station development program is ie a small telescope array CSTAR China Antarctic Research, the plan by the Nanjing Institute of Astronomical Optics Technology, Purple Mountain Observatory, National Astronomical Observatory in collaboration of which the main telescope of Nanjing Institute of Astronomical Optics Technology for Development.
The visit Overall the site organized by the Hong Kong Observatory Antarctic Astronomical Center of the Chinese leadership, China, Australia and U.S. astronomers to participate in cooperation international project have been incorporated into the "International Polar Year," the core of China's action plan? Panda program. Among them, the section CSTAR includes telescope and three games 50cm/75cm Schmidt telescope (AST 3), now Nanjing Institute of Astronomical Optics Technology develops AST3, 2009/2010 provides installed in the Dome A.
CSTAR is 4 sets of 14.5 cm diameter field of view telescope with a rack in the form of a set of small telescopes, the angular field of view is 4.5 ° x4.5 °, focal ratio of 1.2, respectively, white and configuration of g, r, i four types of filters, detectors for 1kx1k frame transfer CCD. CSTAR is mainly for the scientific objectives of monitoring and statistical analysis of variable stars to find extrasolar planets supernovae. To test the telescope on the Antarctic work under extreme environmental conditions, four telescopes were carried out at low temperature test. After such just 10 months time, CSTAR in Nanjing Institute of Astronomical Optics Technology successfully developed, October 10, 2007, through acceptance.
From November 12, 2007, CSTAR as the 24th Chinese Antarctic scientific exploration vessels for Antarctica, January 12, 2008 successfully reached the point top of the continental Antarctic ice dome A. Currently participating in this expedition, two astronomers from Central CSTAR facility and Australia, USA to develop together the site for the measurement of the Antarctic plateau station automatic PLATO observatory.
24th China Antarctic expedition icecap expedition team again on January 12 to reach the highest point of the continental Antarctic Dome A, which is after January 18, 2005 of our country's first human being to reach the ice of Antarctica the ice dome of the earth from a peak once again addressed "human is not near the pole" A. Dome The most striking is that this is the first time astronomers continental Antarctica and reaching the highest point marks the summit of the ice humans in Antarctica are the mysteries of the universe to explore a new milestone.
Dome A is the highest point of elevation of the ice sheet of Antarctica 4093 meters, theoretically expected for the best sites for astronomical observations of a planet. The activities of the Observatory site inspection as part of the "Year International Polar, "the core of China's action plan is managed by the Chinese Antarctic Astronomical Center, China, Australia and astronomers States U.S. to participate in international cooperation projects.
The Observatory site comprehensive study on the Antarctic plateau priority is to establish observatory machine, its main purpose is to determine the parameters astronomical site selection, for the immediate future observations of human behavior Antarctic astronomical ground services for detailed evidence. Astronomical observatories automatically by the engine, the team host, satellite communications, solar panels, automatic weather stations, and the observation of the atmosphere to see (see), background sky, the aurora and a range of facilities. In addition, the Chinese Academy of Sciences National Astronomical Observatories, Nanjing Institute of Astronomical Optics Technology Purple Mountain Observatory and the country was developed jointly by the Hong Kong Observatory Headquarters small optical telescope array CSTAR is the control of Antarctica more than 20 square degrees zenith of all objects inside, to monitor variable stars and statistical analysis of extrasolar planet searches, the supernovas, and so on. CSTAR is the first set of optical astronomical facilities in Antarctica.
According to the State Observatory, Chinese Academy of Sciences, said Yan June, 20 years ago, astronomers began to prepare our country to start the astronomical observations in Antarctica. We have prepared a common application observational program with the United States, and also developed for this purpose had a special atmosphere for the type of Antarctic horizon 40 cm telescope. Unfortunately, for some reason did not complete the program. Astronomers in China this year, with the continental Antarctic expedition aboard the highest point of the first to open the South Pole, led by international cooperation projects in China in astronomy, not only can greatly improve the technical level China astronomical observations, but also for our country in the dark matter and dark energy and the detection of extrasolar planets and other cutting-edge research scientific cooperation in the field in the world advanced level provided a unique opportunity.
The expedition of astronomers to participate in national and continental Antarctica Purple Mountain Observatory Observatory researcher Zhou Xu Zhu Zhenxian Research Associates. As the astronomical community to go to the first expedition to Antarctica to Dome A will be responsible for the installation, commissioning astronomical equipment, establishment of an astronomical observatory task automatically. Nowadays are full of energy, good health, are astronomical for the upcoming construction of the station automatically make the necessary preparations.

Why an optical telescope is a long tube?
Do you see yourself in space or mearly amplify light that reaches us here on earth. Would correct to say that is not in space but that amplifies the light reaching Earth from space?
Optical telescopes do two things. These amplify the amount of light and expand. The long tube is the focal length or distance of the lens or primary mirror to the focal point. When you use a magnifying lens, its focal length is distance from the glass lens of the eye, when the image is in focus. The glass eye lens and are working like a telescope, only without the tube. Magnification is determined by the ratio of the diameter of the eye lens and the focal length of the instrument. A telescope with a focal length mm 2000 mm with an eyepiece 25 is to achieve an increase 80 times. The amount of light amplification is primarily a function of telescope aperture, or diameter of the lens or primary mirror. This is what determines the amount of light entering the scope.

Understanding Foucault
List Price: |
DescriptionDavid A. Harbour presents a brilliant narrative for the Amateur Telescope Maker (ATM), on exactly how the "Foucault Test" is interpreted. Through a series of "foundation lessons" Mr. Harbour ensures the ATM understands what the Foucault Test is revealing, and what to do about it as he figures the telescope mirror to achieve the perfect paraboloid. Imagine if the makers of the Hubble Space Telescope had used this book as a guide to test the HST's primary before launch! The savings would have been in the millions! Well, that may be a stretch, but for the ATM, who has taken on the delightful but challenging task of making his own telescope mirror, how nice it would be to have a guide to ensure success!. Success is at hand. Dave Harbour presents a thorough and informative instruction on just how to be sure the mirror is perfect! This book is for the ATM bookshelf to accompany the classics of Porter, Texereau and others. Features
